   1 GlusterFS Backend
   2 -----------------
   3
   4 Storage pool type: `glusterfs`
   5
   6 GlusterFS is a salable network file system. The system uses a modular
   7 design, runs on commodity hardware, and can provide a highly available
   8 enterprise storage at low costs. Such system is capable of scaling to
   9 several petabytes, and can handle thousands of clients.
  10
  11 NOTE: After a node/brick crash, GlusterFS does a full 'rsync' to make
  12 sure data is consistent. This can take a very long time with large
  13 files, so this backend is not suitable to store large VM images.

  15 Configuration
  16 ~~~~~~~~~~~~~
